Armillaria root rot is a fungal root rot caused by several different members of the genus Armillaria. The symptoms are variable depending on the host infected, ranging from stunted leaves to chlorotic needles and dieback of twigs and branches. However, all infected hosts display symptoms characteristic of being infected by a white rotting ...
Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months.
A dense cluster of fruit bodies growing on a rotting stump. Several studies have shown that the spread of Armillaria root rot in eucalypt forests is associated with infected stumps that remain after an area has been logged. [28] [29] [30] Armillaria luteobubalina can persist on these stumps, using them as a source of food for up to 25 or more ...
Here's a handy guide for diagnosing and treating your lawn's post-summer damage.
This fungus produces a white pocket rot commonly called Tomentosus root rot in both roots and butts of naturally seeded or planted conifers. White spruce and black spruce were found to be the two most susceptible species in an inoculation test in Saskatchewan, [ 6 ] and high losses to root rot, in large part due to I. tomentosus , affected ...
The disease tends to occur in patches due to a primarily short range spread mechanism. [3] Infected or decayed roots break close to the root collar forming “root balls.” [1] Laminated root rot is frequently detected during ground survey when canopy openings and standing dead and fallen trees are observed.
